VIMS Forecast

Gulf of Mexico Dead Zone

VIMS researcher David Forrest forecasts the area of the low-oxygen "dead zone" in the northern Gulf of Mexico based on statistical correlations between the observed area of the Gulf dead zone in August and the average measured discharge and nitrogen concentration of the Mississippi and Atchafalaya rivers during May.

Forecasts based on multiple models are called ensemble forecasts and are commonly used in hurricane and other weather forecasts. The NOAA-sponsored Gulf of Mexico hypoxia forecast is improving due to advancements of individual models and an increase in the number of models used.
